Photovoltaic cells - those black square table that includes a solar panel - is more effective, and progressively cheaper, all the time, with ever better, all drawings concentrate the light of the Sun collected on a more and more concentrated point. The size of cells decreases their effectiveness increases, which means that each cell will become both more productive and less expensive to produce. As the above costs, the price of solar energy production generated by time watt came to $4.00 at the time of this writing. Only 17 years old, it was almost double this cost.
Electricity motor is certainly good for the environment, as this other form of energy production of the absolutely zero emission in the atmosphere and is simply using an of the most natural of all things as a pilot. Cells solar collection become slowly but surely always more convenient for placing them on the roofs of houses of the people, and they are not a system difficult to use for home heating, creation of hot water or electricity. In the case of the use of photovoltaic cells for the production of hot water, the system works by having the water embedded in cells, where it is heated and then sent through your pipes.
Photovoltaic cells become more better to collect enough radiation from the Sun even cloudy or stormy days. A business in particular, Uni-solaire, has developed the solar collection for the House tables that work well on the bad days, a technologically more advanced system that stores more energy at a given time in sunny days than the preceding tables or other.
There is another system of solar energy available for use called PV system. The PV system is connected to the nearest of the electrical network; When there is an excess of solar energy are collected in a particular House, he was transferred to the grid for shared use and as a means of reducing the dependence of the grid on the production of electricity based on the hydroelectrically. Be connected to the PV system can reduce your costs compared than entire solar energy, while at the same time reducing pollution and taking the pressure off the grid system. Some areas are centralized design collection solar tables for small towns or suburbs.
Some big names companies have clearly indicated that they receive in the Act, the use of solar energy (another indication that solar generated energy becomes an economically viable alternative energy source). Google is placing in a plant for generation of solar energy of 1.6 megawatts on the roof of its headquarters, while Wal Mart wants to put in a system of huge 100 megawatts of its own.
Countries such as the Japan, Germany, the United States and the Switzerland have been advance the cause of the production of solar energy by providing government subsidies or by granting tax benefits to businesses and individuals who agree to use solar energy to produce their heat or electrical energy. As technology advances and storage pleased materials solar collection is available, and private investors more will see the value of the investments in this "green" technology and its implementation much more.
